Origin Ver. and Service Release (Select Help-->About Origin): 7.5SR6
Operating System:Windows XP

Is there any way to plot in Origin the Pearson correlation coefficient:
Look in this email:

http://en.wikipedia.org/wiki/Correlation

Look at the section on "The sample correlation" (the Pearson correlation coefficient).
Origin is so good, I think there must be.

Hi Richard,

In version 8, the standard version offers a scatter matrix plot:

and in addition in the Pro version there is a correlation tool which also creates a scatter matrix plot of the results:

You can download the O8 demo (which is fully functional OriginPro) and try.

I am trying to do what you suggest, but this in confusing to me:

3. Select Plot: Statistics: Scatter Matrix from the main menu to open the plotmatrix X-Funciton.

I can select Plot: Statistics - then do I select Scatter Matrix. And what does "from the main menu to open the plotmatrix X-Funciton" mean?

Can you help me further.
